Quettaparma Quenyallo

Imbar place-name "the Habitation, = Earth," also "the principal part of Arda" (= the Solar System) (MR:337, also WJ:419 note 29)

imbë (1) prep "between" (Nam, RGEO:67, VT47:11, PE17:92). This is "between" referring to a gap, space, barrier, or anything intervening between two other things, like or unlike one another (compare enel). The pluralized form imbi implies "among" of several things (ancalima imbi eleni "brightest among stars"); "in the sense 'among' before plurals [imbë] is usually pluralized > imbi even when a plural noun follows". As pointed out by Patrick Wynne, imbi may also be used in the sense of "between" before two singular nouns connected by "and" (as in the example imbi Menel Cemenyë "between heaven and earth"), whereas imbë is used before dual forms, as in the examples imbë siryat "between two rivers", imbë met "between us". Elided imb' in the phrase imb' illi "among all" (VT47:11, 30). A dual form imbit is also mentioned, used to express "in absolute form the sense 'between two things' when these are not named" (apparently meaning that imbit expresses *"between them" referring to two entities, with no noun following) (VT47:30, PE17:92)

imbë (2) noun "dell, deep vale" (VT45:18), ”wide ravine (between high mountain sides)” (PE17:92)

imbë (3) adv. "in(wards)" (obsoleted by #1 and #2 above?). Changed by Tolkien from imba (VT45:18)
